Abstract

A comprehensive overview is given of the representatives of the taxon Gallorhynchus Schockaert & Brunet, 1971: the two known species G. simplex and G. mediterraneus of Schockaert & Brunet, 1971, Syltorhynchus schockaerti Noldt, 1989, which is transferred to the taxon Gallorhynchus, and four new species, G. elegans n.sp., G. faroensis n.sp., G. genista n.sp. and G. bidaformis n.sp..

Schizorhynchia Meixner, 1928 (Platyhelminthes, Rhabdocoela) of the Iberian Peninsula, with a description of four new species from Portugal

“…So far, the study of microturbellarians in the Iberian Peninsula has focused primarily on non-marine environments (e.g., Gieysztor 1931;Farías et al 1995;Gamo & Noreña-Janssen 1998;Noreña et al 1999). The brackish-water habitats of Galicia, Asturias, Cantabria and País Vasco (Noreña et al 2007), the Doñana National Park in Andalusia (Van Steenkiste et al 2011) and the Algarve (Schockaert 2014;Schockaert et al 2017Schockaert et al , 2019 have been investigated to some extent. In total, approximately 100 species of Rhabdocoela have been reported from freshwater habitats in the Iberian Peninsula, the majority of which belong to Dalytyphloplanida (Tyler et al 2006(Tyler et al -2019aVan Steenkiste et al 2011).…”

Only 14 species of Kalyptorhynchia are known from the Iberian Peninsula (Noreña et al 2007;Schockaert et al 2017). Five of these belong to Schizorhynchia: Baltoplana magna Karling, 1949, Cheliplana cf.…”
